Sorry but my previous email did not go through properly. Instead of the ? you should really read an &egrave or &#232 according to http://www.lookuptables.com/.

So there are extended ASCII characters I need to deal with.

I have tried

d1$V1[regexpr("some t&egravext = 9",d1$V2)>0] <- 9
and 

d1$V1[regexpr("some t&#232xt = 9",d1$V2)>0] <- 9

without success...

Thanks,
Luca
